电镀行业适合使用超声波清洗机吗?

来源:/ 时间: 2021-08-13 浏览次数: 2

目前,电镀行业还不太了解超声波清洗机的实际应用,电镀中,前处理的目的为了往除工件表面存在污物及杂质,使其成为合适电镀的活性外表。电镀质量不良的原由较多是前处理不好。而前处理不好,大多未使用亚洲城ca88手机版。
At present, the electroplating industry does not know much about the practical application of ultrasonic cleaning machine. In electroplating, the purpose of pretreatment is to remove the dirt and impurities on the workpiece surface and make it an active surface suitable for electroplating. Many reasons for poor electroplating quality are poor pretreatment. The pretreatment is not good, and most of them do not use ultrasonic cleaning equipment.
超声频率一般为20-100KHZ之间。普通工件的前处理,一般采用低频、中功率的超声清洗设备,如频率25-28KHZ,功率密度1W/cm。
The ultrasonic frequency is generally between 20-100khz. For the pretreatment of ordinary workpieces, low-frequency and medium power ultrasonic cleaning equipment is generally used, such as frequency 25-28khz and power density 1W / cm.、
超声波清洗机
由于低频比高频在介质中轻易发生空化,对于外形简单、并不十分精 密的工件,此类清洗机就能满足要求。特点是噪音较大价格便宜。对一些精 密度较高的工件,现使用的一般都为高频40-68KHZ高功率的超声清洗机。因此类清洗机对于缝隙、间隙、深孔、盲孔等外表形复杂的工件清洗效果较好。但是超声清洗的作用只是有溶液到达的地方才干起到清洗作用。也就是说要避免深孔、盲孔中有空气,并且要留意杂质着落、油污上漂和处置清洗不到位的现象。
Since low-frequency than high-frequency cavitation easily occurs in the medium, this kind of cleaning machine can meet the requirements for workpieces with simple shape and not very precise. It is characterized by high noise and low price. For some high-precision workpieces, high-frequency 40-68khz high-power ultrasonic cleaning machines are generally used. Therefore, this kind of cleaning machine has a good cleaning effect for workpieces with complex external shapes such as gaps, gaps, deep holes and blind holes. However, the role of ultrasonic cleaning is only where the solution reaches. In other words, it is necessary to avoid air in deep holes and blind holes, and pay attention to the landing of impurities, floating of oil and inadequate disposal and cleaning.
电镀前处置时必 须根据工件的实际情况,采用适宜的方法进行有用清洗。金属基材一般分为冲压件和压铸件。冲压件上面的油污为一般冲压油,因其密度相比高所以相比轻易清洗。
Before electroplating, appropriate methods must be used for useful cleaning according to the actual situation of the workpiece. Metal substrates are generally divided into stamping parts and die castings. The oil stain on the stamping parts is general stamping oil, which is easy to clean because of its high density.
一般可用酸洗、电解等。而锌、铝、铜等的压铸件属相比难清洗的因压铸件中添加了各种元素,此外在成型、拉升、压延、切削、抛光的过程中还必 须使用各种油品,如机油、抛光油等。对于超声波清洗机来讲,机油可以轻松往除。但抛光油分为黄油白油、绿油等,这就相比难以往除。因此,必 须选择合适的超声清洗设备和清洗液。
Generally, pickling, electrolysis, etc. can be used. The die castings of zinc, aluminum and copper are relatively difficult to clean, because various elements are added to the die castings. In addition, various oil products, such as engine oil and polishing oil, must be used in the process of forming, lifting, calendering, cutting and polishing. For the ultrasonic cleaning machine, the oil can be removed easily. However, polishing oil is divided into butter, white oil, green oil, etc., which is difficult to remove. Therefore, appropriate ultrasonic cleaning equipment and cleaning fluid must be selected.
工件镀完后固然经过漂洗,但某些较复杂工件,特别是有缝隙、深孔、盲孔的工件(如眼镜弹簧腿)不能起到理想的作用。只有通过用超声波来往除缝隙、深孔、盲孔中残留的电镀溶液。一般在这方面可选择频率略高、功率密度一般的超声波清洗机即可。
Although the workpiece is rinsed after plating, some more complex workpieces, especially those with gaps, deep holes and blind holes (such as glasses spring legs), cannot play an ideal role. Only the residual electroplating solution in gaps, deep holes and blind holes can be removed by ultrasonic. Generally, ultrasonic cleaning machines with slightly higher frequency and general power density can be selected in this regard.
